Home delivery costs a very reasonable £2.95, while store delivery is free. Brantano has 150 shops, nationwide.
To view the sale items, click on Sale on the right hand panel on the Home page. If you can't see it, scroll down the page till you see the Kids sale section. Click on it, then on the relevant category. Other posters over at our sister site said they got Clarks shoes, however there weren't any in the Boys size 10 - 2 section when I looked (or in any other section) so I guess I wasn't quick enough.
There's not a lot on there for boys, but I did spot a very nice pair of Skechers for a boy, reduced from £35 to £24. If you've got an older girl though, you'll be able to find some very nice stocking fillers on here. There's a few pages of reduced shoes in this category, including Winter boots.
